IC Chips

I use a 4 1/2" angle grinder with a thin metal cut off blade and run it along were the legs aare soldered on the back of the board. Ware a dust mask if your going to try this and I only do this on low grade boards.

Desoldering a chip is very simple. You go to radio shack and get a desolder braid. Hold the braid on the pins with a soldering iron and it sucks up the solder. The chip can then just be lifted off the board. This is the ONLY was to remove a chip that you want to reuse. You can practice on capacitors once or twice till you get the hang of it. There are a bunch of vids on youtube that show the proper technique. If you are not going to reuse the chip/board I just use my torch to heat the back of the board and wiggle the chip.

I have made soldering braid from the woven tin plated copper wire thats across the screen on a CRT Tv. Just melted some rosen flux into the braid & used it like that.

Last night I relised that a vacuum pump made from a old fridge motor may be used to suck the solder off too. Like the little hand held solder sucker pumps I see sometimes, but industrial.
